摘要
从辽宁省不同地区尚未使用过甲氧基丙烯酸酯类杀菌剂的保护地采集番茄灰霉病菌,分离获得代表性菌株113株。采用菌丝生长速率法测定各菌株对烯肟菌酯的敏感性。试验结果表明,不同地区的番茄灰霉病菌对烯肟菌酯的敏感性差异不显著;辽宁省番茄灰霉病菌对烯肟菌酯的敏感基线为6.263 4μg·ml^(-1)。
113 isolates of Botrytis cinerea were isolated from protected fields in different regions of Liaoning Province in which the strobilurins fungicide had never been used. Their sensitivity to enestrobiurin was determined by the method of mycelial growth inhibition. The results indicated that their sensitivity was not significantly different between areas. The EC50 6.2634μg·ml^-1 was regarded as the baseline-sensitivity of Botrytis cinerea to enestrobiurin.
